Eat it, don't read it

This is a common saying among non-strict vegans. Instead of searching for such items as 'whey' and 'glycerine' in a long-ass list of ingredients, some people will choose to 'eat it, not read it' and not worry about it. I personally don't see how eating a cracker with one particle of recycled milk product in it is bad, but that's just me. Then again, I'm not vegan at all.
